2. claims: (o1. i6-195) This invention relates to toy air guns pr-oducing the sound of a gun shot by bursting paper with compressed air, and more in particular to a guide and support for a roll of paper in combination with a gun of a type such as is disclosed in my Patent No. 2,083,535. This application is a continuation in part of my copending application Serial No. 123,661, filed February 2, 1937 and issued as Patent 2,265,606.

It is an object of my invention to provide in a. pleasing appearing and efficiently operating combination a paper breaker toy gun and anlimproved holder for supporting rolled paper to feed through the gun.

Another object is to provide a paper holder for suchja gun, which holder Will retain a paper roll againstunrolling to an undesirable amount, or

vbecoming loosened and falling to one side or the other out of the normal rolled position at right angles'to the rotating axis of the roll during all timesof handling of the gun.

' A further object of my invention is to provide a simplified paper holder wherein a portion thereof cooperates in the assembly of the compression chamber of the toy gun in forming an outlet' lfor said chamber at one end thereof.

VA still further object is to provide a holder for Irolled paper for a feeding movement in a continuous strip, with said' holder including a housing conforming substantially to the shapelof the paper roll and having retaining means rotatably mounted thereon for retaining the roll therein.

Yet another object of my invention is-to provide a simplified paper holder wherein portions thereof cooperate in the assembly of the means for sealing a portion of the paper across the out- Alet inthe compression chamber of the toy gun.

FurtherV objects, features and advantages of y my invention will be apparent from the following h description when taken in connection with the.

In practicing my invention, I provide a paper bursting toy gun, having a compression chamber in the barrel thereof, and means for sealing a paper strip across an outlet from the compression chamber to burst the paper with'compr'ests'ed air. The paper is fed in a continuous strip from a roll Lcarried ina housing on the gun barrel, with a portion of the housing cooperating to form the outlet at the end of the compression chamber of the gun. The housingis provided in a substantially cylindrical .casing to. correspond with the form of thepaper roll andv has a paper inserting opening and paper retaining means rotatably To facilitate` reference to my prior patent on that structure which, is common to that patent and to the present application, the same reference characters arezapplied to all common structure. Y

Fig. 1 illustrates a toy gunof a type such as is disclosed in y my prior patent kreferred to above,

`having a handle Il and a trigger member 63 adapted to be grasped by the user, with the trig- Ager operating'throngh the spring and'release mechanism described in my patent, and including a piston 26 (Fig.l 2) and compression spring 34 carried thereon. I A two-piece gun barrel I2 carries a cylinder lI6 in the front end thereof,

'the gun barrel being formed With'portions I8 which are adapted to be bent into cooperating apertures -IIJ in the cylinderwalls for locking engagementwiththe cylinder I6. TheV piston and spring mechanism are entirely enclosed within the gun,the piston having a metal washer 20 on the end thereof engaging the inside .wall of the cylinder I6 to compress the air therein as the piston is moved forwardly under spring pressure clearly embodiments of the present invention, a stripof paper 41 is sealed across the outlet from the cylinder I6 to be burst by the discharge of air through such outlet. The strip of paper 41 is fed from a roll of paper I by paper sealing and feeding mechanism including a metal slide designated generally as 45 and having a front end or sealing portion 48 anda movably carried feeding jaw 53 on the top of the slide having teeth at its end 51 engaging the paper 41 and extending to a feeding plate 39 intergral with the mounting or plate portion 31 for the roll carrying housing 16 as will be hereinafter described. The plate portion 31 has an aperture thereinsurroundedby an upset flange 3l) (Fig. 2) `which ispressed'over the inwardly flanged end 4360i the cylinder I6 to rigidly mount the paper carrying housing 16 on the cylinder and barrel assembly of the gun. A rubber grommet 4I is adapted to be retained at the cylinder outlet by a cooperating assembly with the flange 3,8, the rubber grommet provid- Aing acushion against which the sealing portion 48 presses the paper 41 to provide an air tight Aseal over the compression chamber outlet to make possible the bursting of the paper with a loud noise.

' My air gun is a repeating device and will fire or burst the paper as rapidly as the operator may compress the trigger member 63 with his ngers A,to cock the gun and permit the release of the piston 26.

The preferred embodiment of the combination :is illustrated in Figs. 1 rto 3, inclusive, and shows the-housing for vcarrying the roll of paper 5I supported below the gun. The housing includes :a substantially cylindrical casing portion having lone end thereofblosed by an integral side 'wall I3. `The mounting portion 31, casing por- ."tlon' 35, and side wall I3 are formed from a single piece'of sheet metal. jcasing 35 is adapted to beV closed by a slidable The opposite end of the door I4 which is rotatably supported on -axis means 59 located intermediate the mounting portion 31 and the casing 35. The casing 35 at a point substantially opposite from the pivot means :59 is formed with an axially projecting lip I1 which releasably engages a recess or notch 60 in lthe door I4, to hold the door I4 in a closed position'. With thef'd'oor I-4 opened, therefore, the

The mounting portion 31 on opposite sides of the aperture 30 therein -is formed with vertically extending flanges -6I positioned on each side of Vthe gun barrel I2 and bent inwardly of the gun.

Each ange SI substantially intermediate the ends thereof, has a, cut-out portion I9 or guideway, with each guideway I9 being adapted to slidably support a corresponding one of the pair of guide arms 2l on the metal slide 45. As is apparent from Figs. 1, Zand 3 the guide armsv 2I are integrally formed at one end with the sealing portion 48, while their opposite ends are operatively connected as by a pin 22 with the spring and release mechanism which is fully explained in my prior patent. On operation of the gun, therefore, the sealing portion 48 is moved to the compression chamber outlet by the slidable support of the arms `2I in the guideways I9. The

Vmounting lportion 31., therefore, not only serves to rigidly mount the paper carrying housing 16 on the gun, but is formed to cooperate in the assembly of the compression chamber within the cylinder I6 and of the means for sealing a portion of the paper 41 across the compression chamber outlet.

A further embodiment of the combination structure is illustrated in Figs. 4 6, inclusive, and includes a housing 23 supported above the gun and having a casing 24 which extends downwardly to the mounting portion 31 and upwardly in cylindrical form to a. point 25 on the housing 23 which is located substantially opposite the mounting portion 31, as is clearly shown in Fig. 6. A slidable cover 62 is rotatably supported at apertures 21 in the casing side walls 28 bent to right angles with the casing 24 and formed integral therewith through a connecting portion indicated in Figs. 5 and 6 as 64. The cover 62 is shown in full lines in closed position (Fig. 4) to retain the roll of paper 5I therein, while the dotted lines in Fig. 4 indicate the cover in open position.k A projection'29 on the casing 24 serves -to releasably lock the: cover 62 in closed position, while the opening of the cover is facilitated by a. bevelled portion 3| (Figs. 5 and 6) which helps to guide depression 32 over the projection 29 to readily open the cover. A guideway 33 centrally of the cover and guideways 65 adjacent the edges iit over the projection '29 and beads 66 respectively, as the cover is moved to an open position. When the cover is in closed position, a slot formed by the lower edge 40 Vof the 'cover and the bend 38 intermediate the casing 24 and mounting portion 31 forms a guiding opening to guide the paper from the roll 5I into the Yfeeding mechanism of the gun.

Yet another embodiment of the combination structure is illustrated in Figs. 7 and 8 in which the housing 61 is supported above the gun and includes a semi-cylindrical casing 42 and integral side Walls 43` and 44 bent to right angles with the casing 42 and `connected thereto by short connecting portions as indicated at 46 in Fig. 8. The casing 42 with its .integral side Walls 43 and 44 extends downwardly to the mounting plate portion 31, the casing 42 and mounting portion 31 being stamped out from a single piece of metal. As previously described, the mounting portion 31 is provided with a flanged aperture for securing the mountingportion, and in fact 'the entire housing 61 to the cylinder 'I6 in the vgun proper. 'Ihe casing 42 extends from the 'bend 3B to terminate peripherally in a curved integral lip 68 which is formed so as to, engage the transverse or handle portion 49 of the roll retaining member`50 in a substantiallyispring catch action.

The retaining memberl 50` is formed from wire substantially of the size indicated'A in Fig. '1 and includes a transverseaxis portion`52 anda radial arm 53 Vextending `to the handle portion 49. The radial arm portion 53 is of a vlength slightly greater than the radiusof the circular wall 44. The member 50 is rotatably mounted in correspondingly positioned apertures 54 and 55 in the side walls 43 and 44, respectively, of the housing. In the original mounting of this member the 'normal sized outer end of the portion 52 is inserted through aperture 55 and Vthen flattened outin any desired manner to theconiiguration at 58 Ishown particularly in Fig, v8. This flattened end 5B may be inserted through the corresponding `aperture 55 in the opposite side wall of the housing. To insert the paper rol-l 5I in the housing, the .handle portion 49 is snapped out of thelip 68 and brought forwardly until the flattened` end `58 may be withdrawn throughtheslot `54, after which the vpaper roll 5l is inserted in the Walled housing, and the retaining member 50 reinserted through the slot 54 and moved to the position shown in Fig. 8. In a commercial embodiment of the structure it has been found that the paper roll is amply protected against damage, feeds satisfactorily out of the housing, and is retained by the walls 43 and M from falling to one side or the other.

In utilizing only a two-piece assembly for the complete housing for the paper roll, and then employing the mounting portion of that housing to cooperate With the barrel and cylinder structure of the gun to complete the gun assembly in providing an outlet for the cylinder and a slidable support for the paper sealing means at the cylinder outlet, a minimum of material is used without in any Way sacrificing ruggedness, simplicity, and the artistic merit of the gun combination.

Although the invention has been described in its preferred embodiments, it is to be understood that it is not to be so limited since modications and alterations therein can be made which are within the full intended scope of the invention as defined by the appended claims.
